What is a flush sash window?

Flush sash windows look great installed in any style of property. Whether you live in a contemporary townhouse in Tiptree or a country cottage in Kent, their sophisticated style will add a touch of class to your home. Flush sash, also known as flush casement windows, are characterised by frames that sit flush with the external face of the window. When closed, the window sash is level with the outer frame creating a smooth and even finish. The sash is the part of the window that holds the glass, and the framework around the glass, to keep it in place.

Had my front and back door changed. Kamlesh was very professional, he came to inspect the property and provided a quote. We went online and order which door we liked (type, colour, door furniture). 4 weeks later it was ready and they installed it in 1 day. Everything works great and they were a pleasure to deal with.

Extremely happy with the work carried out of having new windows and front door installed. Having these changes have made our home not only look different but warmth and something to be proud of. Great work by Kamal and his team would highly recommend them to anybody and definitely use them again near future.

Great little company! We commissioned them to install a porch and we were VERY particular about the style, profile and dimensions. Kam worked with us to come up with a design that we were happy with and the installers were brilliant, with a real attention to detail. We had an issue with the brick laying but they had it all taken down and redone for us, so we were happy with the solution. Our porch is the best on the street! Recommended
